As many of us living in southern Arizona know, it’s been a comparatively dry monsoon. Normally, in my neck of the desert, Bear Canyon creek is running from all the rain dropped in the Catalina Mountains by summer monsoon storms. As of today, it is dry as a bone from the trailhead crossing on up to the last remaining pools.
However, a storm system is moving our way from the south (remnants of Lorena) and the forecast is 70% rain Monday and 80% Monday night. I’m so hoping for a localized drenching where the washes flood and Bear Canyon creeks flows again. Here’s an aerial I took of upper Bear Canyon at Seven Cataracts after winter rains earlier this year:
Camera traps are one of the best ways to observe wildlife behavior that you’d likely not see because it’s either dark out or your presence would alter the animals behavior. I bought my first camera trap around 2005 and was instantly addicted. I had no idea there were such shenanigans happening when I wasn’t around.
Now, in 2019, I have about 10 personal cameras set up in the desert around my home town, Tucson, including my backyard. I also have another 10 cameras set up at Audubon’s Appleton-Whittell Research Ranch near Elgin, Arizona. We use these cameras for long-term wildlife monitoring, recording which animals and how often pass through the research ranch.
In this post I’d like to share some backyard wildlife action my cameras recently captured.
The Queen and Monarch butterfly season in my pollinator garden was pretty subdued this summer. Not sure if it was the dismal monsoon season with very little rain or other factors. I did manage to catch a couple stages of metamorphosis of a queen butterfly.
First, watch a queen caterpillar turn into a chrysalis:
And the next step is the fully developed butterfly emerging from its chrysalis:
For the third year and second time this summer a Broad-billed Hummingbird raised a new batch of hummingbirds in a re-used nest in my patio. Both the first clutch and the second (seen below) from this summer had two eggs, but only one from each clutch was viable and successfully fledged.
Here’s a photo of the two nestlings from last summer’s clutch:
Here’s a male Broad-billed hummingbird I photographed at one of my feeders, fully displaying his sexual dimorphism.
Finally, here’s a video of the female feeding her one nestling from the last clutch of this summer:
While I am still in Costa Rica, I wanted to share a short video of many, but not all, of the mountain lions my trail cameras captured in 2018. Not sure how many individuals are represented here, though I’m thinking around 8 or 9, based off location and physical characteristics. Feel free to comment if you have a guess or know an easy way to visually distinguish individuals. Enjoy!
This little Broad-billed Hummingbird is likely the same one that built a nest in my patio last summer. Either way, she was able to successfully fledge two youngsters. There were plenty of hanging-plant options on which to build her nest, but she chose the green hook.
During her time incubating the eggs and feeding the nestlings the temperature in the patio was between 100 and 111 degrees (38 to 44 c.). She had her work cut out for her.
Here she is incubating her eggs:
Here she is feeding her kids a few days before they fledged:
